If an enemy faction conquers the Citadel of a faction and holds it through the contested period, the defending faction is defeated.

All the players in the defeated faction who participated the war and defended their homeland will receive a special 'Homeland Defense Reward'.

In the meantime, they will be given an option to join another faction. The following is all you need to know when changing your faction:

1) You have 10 days to decide and join another faction. This process includes two steps: 3 days of Consideration Period and 7 days of Decision Period.
2) During the Consideration Period, you can discuss with your friends or your guild which faction you want to change to.
3) During the Decision Period, the [Change Faction] button will be enabled in both the Guild page and your Profile page. You must change your faction before the 'Decision Period' ends. Otherwise, the system will randomly pick a faction for you.
4) Your Guild leader can change faction for all members, so talk to your guild first before making a decision. Co-leaders cannot make this change.
5) If your Guild leader is inactive, you can quit your Guild and then go to your Profile page, select Faction, and then change your faction from there.
6) If you don't want to join the faction your Guild leader chooses, please quit your Guild before the Consideration Period ends, and then go to your Profile page, select Faction, and then change your faction from there. Once your guild leader changes faction for all members, you can no longer change your faction again.
7) When you successfully join another faction, your city will be teleported, and you will be gifted an 'Advanced Teleport' so that you can move your city to a location at your choice.

IMPORTANT, once your faction is changed, it cannot be undone. Therefore, if you don't want to join the faction your guild leader chooses, make sure that you quit the guild before the consideration period ends.
